CRESSI MC9 SC + COMPACT PRO REGULATOR

CRESSI MC9 SC + COMPACT PRO REGULATOR

The Cressi MC9 SC + Compact Pro Regulator is a compact, lightweight, and high-performance scuba regulator designed for smooth breathing, dependable airflow, and reliable performance in both warm and cold-water diving conditions. Combining the balanced diaphragm MC9 SC first stage with the ultra-compact Compact Pro second stage, this regulator is built for divers who want comfort, durability, and advanced protection in a travel-friendly setup.

The MC9 SC first stage features Cressi’s PressureSync technology, which helps maintain consistent intermediate pressure throughout the breathing cycle. This reduces pressure fluctuations and provides a smoother, more comfortable breathing experience underwater. The balanced diaphragm design delivers reliable airflow, while the environmentally sealed chamber helps protect internal components from freezing, water, debris, and contamination.

A high-capacity conical filter with a large surface area helps trap impurities from the cylinder, making this regulator especially practical for travelling divers using rental cylinders. The electroless nickel-plated first stage adds durability and corrosion resistance, while the compact T-shaped port arrangement improves hose routing without adding unnecessary bulk.

The Compact Pro second stage is made from thermoconductive polymer, a lightweight material that helps transfer warmth to the internal components to reduce the risk of ice formation. Its adjustable Venturi system allows divers to optimise airflow during the dive and reduce free-flow at the surface. With a large purge button, impact-resistant front cover, and ultra-light 140g second stage weight, the Compact Pro is built for easy, comfortable, and dependable use.

Specifications

Technology

PressureSync Technology
Helps maintain consistent intermediate pressure throughout the breathing cycle, reducing pressure fluctuations and improving breathing comfort.

Environmentally Sealed First Stage
Keeps the first stage chamber dry, helping protect internal parts from freezing in cold water and contamination in silty or dirty conditions.

High-Capacity Conical Filter
A larger filter surface helps trap more impurities from the cylinder, protecting the regulator and improving reliability, especially when using rented cylinders.

Thermoconductive Polymer Second Stage
Lightweight material that helps transfer warmth from the water or diver’s breath to internal components, reducing the chance of ice formation.

Adjustable Venturi System
Allows divers to maximise airflow during the dive and help prevent free-flow when the regulator is at the surface.

Application

Perfect for recreational scuba diving, cold-water diving, warm-water diving, travel diving, and divers who want a compact regulator with reliable airflow and advanced protection. Ideal for divers who need a smooth-breathing regulator that performs confidently in a wide range of conditions.

Compact, smooth, and cold-water ready — the Cressi MC9 SC + Compact Pro Regulator delivers dependable breathing performance with lightweight comfort and advanced first-stage protection.
